Android: Google announced a number of updates to Google Play at Google I/O today, including movie purchases to go with the already-available movie rentals, magazine subscriptions from major publishers, and "smart updates," where your Android device only downloads the updated parts of an app you have installed, instead of the whole app over again.

While Google didn't make mention of when these changes would be live, they did mention that smart updates at least would work with all Android phones running Gingerbread or higher. Movie and TV show purchases are available through partnerships with studios like Disney, Sony, NBC, and more. Magazine subscriptions are available through publishers like Conde Nast and Hearst, and include titles like Esquire, Shape, Wired, Parenting, to name a few.

Also worth mentioning are some of the updated Google apps bundled with the new Nexus 7 tablet. An updated version of Google Currents, one of our favorite newsreaders, is bundled with the Nexus 7, which includes Google Translate built-in, so you can switch languages on the device with a single tap. The Nexus 7 also sports a new version of Google Maps with a built-in compass and entirely offline maps and directions. The tablet also has a new media manager, which makes it easier for you to find the music, magazines, TV shows, and movies that you've downloaded, and suggests new ones to you based on what you've watched already.
